Keppel Shipyard to convert
VLCC into Liza FPSO
SBM Offshore has contracted Keppel Shipyard Ltd. to convert a
very large crude carrier (VLCC) into an FPSO for ExxonMobil’s Liza
oil field development offshore Guyana. Liza is in deepwater, about 193
km (119 mi) offshore in the Stabroek block.
Keppel’s scope includes refurbishment and life extension works,
such as upgrading of the living quarters, fabrication and installation of
spread mooring systems, and installation and integration of topsides
modules. The converted floater will provide a crude storage capacity of
1. 6 MMbbl, production of up to 120,000 b/d, gas treatment at around
170 MMcf/d, and water injection at around 200,000 b/d. The vessel
will be spread moored in 1,525 m ( 5,003 ft) of water.
MODEC wins Sépia FPSO assignment
Petrobras has awarded MODEC Inc. the charter and operation
services contract for the Sépia FPSO. The firm charter period is 21
years. The FPSO will be deployed at the Petrobras-operated Sépia
field in the presalt Santos basin about 250 km (155 mi) offshore Rio
de Janeiro. Water depth is about 2,200 m ( 7,218 ft).
MODEC is responsible for the engineering, procurement, construc-
tion, mobilization, installation, and operation of the FPSO, including
topsides processing equipment as well as hull and marine systems.
SOFEC Inc., a MODEC Group company, will design and supply the
spread mooring system. The FPSO will be capable of processing
180,000 b/d of crude oil, 212 MMcf/d of gas, 240,000 b/d of water
injection, and will have a storage capacity of 1. 4 MMbbl of crude oil.
MODEC and Petrobras said that the vessel will be delivered with
Brazilian local content.
Bureau Veritas addresses FSRU classification
Bureau Veritas (BV) has published a new Rule (NR645) for classification of floating storage and regasification units (FSRUs). This
sets out the requirements for addressing the technical and operational
issues for units that may operate as a floating terminal for one or more
decades to FSRUs operating for much shorter periods, and whose
owners may want the option of trading as an LNG carrier.
The rules address all these needs, BV says, while applying a uni-
fied approach to safety and design challenges and providing clarity
by offering two distinct class notations:
Liquefied Gas Carrier - FSRU notation: Based on rules for the clas-
sification of LNG carriers: this enables gas trading in addition to floating
storage and regasification terminal operations. The notation also provides
for possible exemptions from the traditional class survey regime, such
as five-year drydocking surveys, when the vessel is in use as an FSRU.
FSRU notation: For units dedicated solely to gas storage and
regasification terminal operations. This notation is said to provide a
class survey regime as applicable to permanent units with continu-
ous operation requirements. No drydocking would be necessary,
and some exemptions are allowable from IGC Code requirements
compared to typical LNG carriers. For example, there would be no
bottom damage stability requirements, having addressed specific
Jean-François Segretain, Marine Technical Director, Bureau Veritas,
said: “FSRUs are a special market with both ‘marine’ and ‘offshore’
approaches and requirements involved. So, FSRU projects raise a lot
of questions from all stakeholders.
“These new rules take into account the specific technical, regulatory,
operational and environmental requirements of FSRU stakeholders to
provide a much higher level of confidence when making significant
Third icebreaker set to deploy at Sakhalin- 2
PAO Sovcomflot (SCF Group) has named its latest multi-functional
icebreaking standby vessel (IBSBV) for the Sakhalin- 2 project offshore
eastern Russia the Fedor Ushakov. This is the third of four icebreak-
ing multi-purpose supply and support vessels under construction
for the project at Arctech Helsinki Shipyard (a subsidiary of United
Shipbuilding Corporation JSC).
The latest vessel is named after Admiral Fedor Ushakov (1745-1817),
who was instrumental in the foundation of the port of Sevastopol and
the development of the Russian Navy fleet in the Black Sea. It will
operate flying the flag of the Russian Federation, the port of registry
being St. Petersburg, with a 28-strong crew.
The 3,824-dwt IBSBV measures 99.9 m (328 ft) in length, 21. 6 m
(71 ft) in breadth, and 7. 6 m ( 25 ft) in draught. The Russian Maritime
Register of Shipping, which is providing technical supervision during the construction of all four vessels, has assigned an ice class of
Icebreaker 6 to the new vessel.
The icebreaking supply vessel Gennadiy Nevelskoy and the IBSBV
Stepan Makarov were delivered earlier this year. All the ships are
designed to operate in ice conditions in the Sea of Okhotsk, with the
design and equipment said to ensure the year-round safety of personnel working on the three Sakhalin- 2 offshore production platforms,
and with equipment to respond swiftly to emergencies.
Drydocks World to overhaul Lancaster FPSO
Bluewater Energy Services and operator Hurricane Energy have
awarded Drydocks World two contracts for the Lancaster early production system project. The yard in Dubai will perform a repair, life
extension, and upgrade project on the FPSO Aoka Mizu, which formerly
worked for Nexen in the central North Sea. In addition, Drydocks
World will fabricate a 1,000-ton turret buoy to help the vessel moor
and weathervane at the field location west of Shetland. Hurricane
Energy anticipates first oil during 1H 2019. •
